Title: Recreational sled
Inventor: MCMILLAN DAVID J
IPC: B62B13/00
Filed: 1991-04-26
Abstract: ABSTRACT      A sled for gliding over ground gliding surfaces, such as snow-covered downhill surfaces, and including an intermediate portion forming a passenger carrying deck, and having a pair of runners at either side of the deck with the deck being connected to upper portions of the runners.  The runners have forward portions of running edges thereof convexly curved with an increasing acute curvature towards the front ends thereof.  The running edges engage the gliding surface from an initial forward point of contact over a distance extending rearwardly to the rear end portion of the runner.  The runners are connected to the deck by separate connector members, or the runners, deck and connector members are formed as an integral molded unit.  The runners are disposed at an angle to the vertical so that the running edges are disposed laterally outwardly from the deck.  The deck and/or connector members provide sufficient resiliency between the runners to permit a scissor action which accomplishes a steering effect as a downward force is applied to the front end of one runner while an opposite upward force is simultaneously applied to the other.

Title: Generation and selection of novel dna-binding proteins and polypeptides
Inventor: LADNER ROBERT C
IPC: C12N15/09
Filed: 1990-01-05
Abstract: Novel DNA-binding proteins, especially repressors of gene expression, are obtained by variegation of genes encoding known binding proteins and selection for proteins binding the desired target DNA sequence. A novel selection vector is used to reduce artifacts.  Heterooligomeric proteins which bind to a target DNA sequence which need not be palindromic are obtained by a variety of methods, e.g., variegation to obtain proteins binding symmetrized forms of the half-targets and heterodimerization to obtain a protein binding the entire asymmetric target.

Title: Publication personalization
Inventor: DOANE I GERALD
IPC: B41J21/00
Filed: 1992-06-30
Abstract: A method and apparatus provide for the personalization of magazines and like "book" publications. A book, having a cover which provides address information, is formed from a number of signatures. This is accomplished by automatically printing at least one personalized signature with variable personalized printing (such as by ion deposition), assembling the personalized signature with at least one other signature, detecting the personalized printing on the personalized signature (as by optically scanning OCR characters), and in response to such detecting, printing address information on the cover. The personalized printing can be the addressee's name, photograph, or identification number. The personalized signature may be assembled with other business documents, such as a business reply envelope, and may be perfed to provide a return form. Alternatively, complete address information may be printed on the signature and a die cut window formed in the cover, through which the address information is visible once the book is assembled. All of the books having address information with common postal codes are produced in a sequence -- regardless of the demographic form of the signature that has been personalized -- so as to maximize the chances for securing a minimum postal rate.
